The Heat / Cool setpoints and address assignments are stored in
non-volatile memory to insure recovery in the event of a power inter-
ruption. Thermostats are powered with 24vac, and communication is
through the RS-485 twisted pair (Belden 8740) communication wire.
COMMUNICATION WIRE SPECIFICATION RS-485
The
Commander
System sends and receives data from the Command
Center to all communicating devices through a 2-conductor twisted pair
RS-485 link (Belden 8740). The communication wire has a maximum
run length of 4,000 L Ft. The communication link is a vital component
of any DDC system, and it must be installed correctly using the correct
wire for the specific application.
For standard applications the basic twisted pair (Belden 8740) wire is
used, which is daisy chained to each communicating device. For
installations with any potential for electrical interference such as caused
shielded twisted pair (Belden 8450) should be used to insure clean
communications.
